Fords M55 exhaust- will i lose boost?

[DaFly]

i want my car to be as loud as possible. i currently have JBA's, 2-chamber Flows, and o/r h-pipe. i keep reading about FRPP M55 3" cat-back, its supposed to be super loud. but my question is with that addition, will i suffer a 1 or 2 psi of boost, due to lack of back pressure? im stilla newbie, so sorry if this sounds way out there. thnaks!

**ALSO** If any body has sounds clips of it, pleeeaaaase post them!

No boost loss.... just hearing loss.

I've got an 04 with the M55 and a Flowtech O/R X.... I just bought some bassani baffles because the damn thing is too loud (I know, I didn't think there was such a thing as too loud either).

...oh yeah, the reason the M55 is so loud is that it doesn't really have what you could consider a muffler.

The muffler canister has a solid pipe through it so with little gaps at the ends that open into the body of the muffler. The effect of this is that once the rpms go over 3.5K and the exhaust gas is moving fast enough its like having straight pipes, and behind the muffler its all 3" pipe so the thing screams.

Whoa, never heard of this. Sound clips anyone???

Somebody had posted some of the M55 with the stock H on svtperformance a while back, don't know if they're still on there though.
